Performance, scalability, and shared resources were the primary focus of initial cloud offerings. Cloud computing has matured and established itself as yet another option for IT including sensitive data is making its way to the cloud.
Organizations are beginning to realize that the cloud does not lend itself to static security controls. In the cloud, security solutions must have the capability to interpret its context, intercept all data traffic, and then make appropriate decisions about that traffic. The cloud requires the ability to apply policies and tools that can control access to, and migrate with, the applications and data as they move from traditional data center to cloud—and as they travel to other models in the cloud.

Organizations are consuming software-as-a-service (SaaS) applications at an exponential rate. While the advantages of SaaS applications are great, so are the potential pitfalls of unauthorized access. As these applications become increasingly popular, an affordable, manageable solution that oversees and controls user access to SaaS-hosted information becomes more crucial. Security, compliance reporting and ease of access are all issues at the top of the list of concerns, and organizations must handle these correctly. Unless they consider complexity when evaluating how authorized access is secured, they’ll settle for a solution that’s incomplete, insecure and requires manual intervention.
Cloud computing has brought a new paradigm into the marketplace. IT budgets remain static and business units are becoming the budget drivers. Often, capital spending is the first expense that organizations defer, delaying new business models that would enable both business units and IT to work more efficiently. Thus, organizations are embracing a new way of consuming applications: software as a service (SaaS).
Using SaaS applications, your organization can forego the upfront costs typical of new deployments and move fast in a way that is simply not possible with traditional applications. In addition, SaaS provides three major benefits over the traditional way of purchasing software:
- SaaS applications are hosted in the cloud and accessible from anywhere.
- Mobile access is readily available.
- IT isn’t tasked with update projects to get the latest features or fixes—the applications are always up to date.
With these clear advantages, it’s no wonder that the SaaS market is growing at an astounding rate. In 2011 it reached $21.2 billion, and is projected to grow to $132.5 billion by 20201. Gartner anticipates the fastest growth rates by 20162.
